A Rudimentary Framework Of The Emergence Of Naturally-Occurring Mentorships, Aaron S. Baker Cervantes

Dissertations

Cross-age relationships between youth and adults that develop organically outside the construct of youth programs are examples of natural mentoring relationships. In the United States, research has demonstrated the positive impact of these mentorships. Scholars have begun applying concepts learned from natural mentoring to formal mentoring schema; however, much work is yet to be done in examining how these relationships emerge and the factors that impact their development. Designed in partnership with a private secondary school in rural México, this study aimed to unpack these questions using a grounded theory approach. Current students, alumni, and teachers participated in the study …

Relationship Between Social Support And Stress In Accelerated Nursing Students, Karen L. Bravo

Dissertations

Nursing program attrition rates and retention rates in the first year of professional practice are excessive due to stress. Investigating through this quantitative, correlative research study is due to the lack of information related to accelerated students and stress. Theories framing this study, the Transactional Model of Stress and Coping, and Triadic Reciprocal Determinism Theory, posit that the environment, whether internal or external, affects stress reactions. The research questions included relationships of Significant Other Support, Family Support, and Friend Support to Perceived Stress Score in a two-part online survey of 116 United States participants.

Racism Without Race: The Racialization Of Middle Eastern And North African Students At U.S. Colleges, Hannah Mesouani

A Double-Edged Sword: Lived Experiences Of Hispanic/ Latino Nursing Students Who Speak English As An Additional Language, Esmeralda Araceli Clark

Dissertations

As the population of the United States continues to become more diverse, the nursing profession is working toward diversifying its nursing workforce. Diversification of the nursing profession is linked to improved patient outcomes and culturally competent care. The experiences of minority nursing students with English as an additional language (EAL) have been studied including some interventional studies. Still, there is a gap in exploring the experiences of Hispanic/Latino nursing students with EAL. The literature described EAL as the most significant risk factor for non-acceptance into a Bachelor of Science in Nursing program for any group of otherwise qualified applicants. Since …

Threading Memory: Performing Animacy In Text, Memorial, And Travel, Alex Keith Davenport

Dissertations

This dissertation explores the process of creating and touring a community-sourced memorial quilt for the anti-mountaintop removal activist Julia “Judy” Bonds, who died in 2011. As a practice, the project positions memorialization as a possible framework for social movements to utilize when faced with loss that allows for actions that honor members of the movement while still engaging in consciousness raising and organizing efforts. From a theoretical standpoint, the practice of memorialization—especially when it is intentionally designed to align with the practices/legacy of the person(s) being remembered—is also considered through an object oriented ontology perspective, providing insight into the affective …

Decoding The Public Service Announcements (Psas) Of Hiv/Aids: Evaluating Botswana's Aids Messages And Their Impact On 15 - 24 Ages, Enole Ditsheko

Dissertations

The study is grounded in the concept of “Start where the people are” (Nyswander, 1956) which suggests that effective health campaigns that promote prevention strategies to enhance the quality of life for those targeted must be rooted in the prevalent cultural practices and religious values of the receivers of the slogans, themes, and taglines. Health campaigns that superimpose the values of the outsiders promoted as universalized solutions have limited effectiveness.

Sub-Saharan Africa has only 1.3 billion people out of an estimated eight billion of which China and India each recording above two billion, cumulatively accounting for more than half of …

Felicidad Aplataná: How Dominican Migrants Living In The Nordic Countries Make Sense Of Their Happiness, Ivanna Lajara

Dissertations

As globalization evolves and the number of migrants and cross-cultural interactions among world citizens increases, understanding various aspects of immigrants’ experiences, including their happiness and subjective well-being will become fundamental to organizations, governments, and societies. However, there are substantial cross-cultural differences in how people understand their happiness, make sense of experiences that influence happiness, and how large-scale social trends, such as globalization, relate to the individual migration perspectives (Uchida and Ogihara, 2012). Research affirms culture as a key factor influencing happiness (Ye et al., 2015) and living in a foreign country may not only impact one’s perspective on life, but …

Essays On Agglomeration Economies And Industrial Clusters, Ahmad Aswin Masudi

Dissertations

This dissertation explores the role of agglomeration economies in Indonesia’s manufacturing sector. In three chapters, I utilize different methods from three different perspectives.

The first chapter explores the role of localization and urbanization economies in manufacturing firms’ location decisions using Indonesia’s Industrial Survey from 2003 to 2013. The mixed conditional-multinomial logit model results indicate that, despite the small magnitudes, localization economies do attract firms. However, urbanization economies seem to discourage firms. On the other hand, sectoral-weighted import content has proven to be one of the most prominent attractors of firms, except for medium technology firms in Java. For foreign firms …

Exploring The Information-Seeking Behaviors And Decision-Making Processes Of Couples In Response To Unfamiliar Tornado Threats, Chih-Chun Rosie Lin

Dissertations

The unique disaster, tornado, causes significant damage and casualties in the US every year, and tornado warnings are crucial to helping people take protective action and reduce the negative impact, especially in an unfamiliar situation. It is important for authorities to better understand how households in low-risk areas rely on information, perceive risk, and make protective action decisions because tornadoes can occur in many geographic locations and might cause significant damage.

Capturing Maximum Photovoltaic Power With Machine Learning: Maximum Current Prediction, Mppt Methodology, And Adjustable Ml-Based Controller, Zahi Mohamed Mohamed

Dissertations

The primary aim of this doctoral thesis is to examine the potential application of machine learning (ML) in optimizing Maximum Power Point Tracking (MPPT) and devising a flexible ML-based controller for photovoltaic (PV) systems. The lack of MPPT mechanisms leads to fixed voltage and current points for PV modules, resulting in substantial power loss when environmental conditions vary. The limitations of conventional and enhanced MPPT methods, as well as finding an alternative controller to classical Proportional-Integral (PI) controllers, have spurred the search for substitute approaches to maximize PV power. To address these limitations, this thesis proposes using ensemble ML techniques, …

A Multiscale Linkage Between Riverscape And Fish Community Coevolution, Loren W. Stearman

Dissertations

Sediment dynamics are foundational to stream and watershed morphology. Yet aquatic ecologists have relied on an oversimplified model of sediment dynamics characterizing sediments as agents of stream bed burial, and which fails to describe many types of aquatic habitat evolution. In this dissertation I employ both fluvial geomorphic and ecological frameworks to gain a deeper understanding of how sediment dynamics shape stream morphology and fish community evolution at multiple scales. Using a paired historic and contemporary approach, I analyzed geomorphic evolution and fish community change in the Bayou Pierre, Mississippi, from the 1980s to recent. Patterns of erosion due to …

Transportation Managers’ Perceptions Of The Diffusion Of Innovation Within Logistics Clusters, Stephen Mcdonald Puryear

Dissertations

The human capital capacity for innovation is crucial for business success. Cluster theory posits that this capacity for innovation is enhanced by industrial clustering geographic proximity. The innovative capacity is expected to be facilitated by institutions for collaboration, informal knowledge flow, short feedback loops, and collective action regimes. Research on logistics clustering has supported this supposition. Still, no research has explicitly examined whether being physically located in a logistics cluster enhances a company’s human capital capacity for innovation.

This study uses the Interpretive Phenomenological Analysis (IPA) approach to determine the innovative operational processes involved in the diffusion of innovation within …

The participant selection involved purposeful sampling of various stakeholders engaged in interviews and focus groups, including faculty, nursing students, and nurse managers with …

Community-Based Early Dementia Advance Care Planning In The United States, Christine Noelle Flaherty

Dissertations

Dementia Advance Care Planning (ACP) promotes quality of life through discussions and decisions about goals of care and end-of-life wishes. However, ACP is rarely introduced in the community setting, and ACP is commonly deferred until advanced dementia when the patient can no longer communicate. The purpose of this three-manuscript dissertation was to advance the understanding of community-based early dementia ACP through an examination of the literature (manuscript one), the development of the dementia public health exposome conceptual framework (manuscript two), and the exploration of perceptions of ACP amongst dementia clinicians, dementia caregivers, and individuals with preclinical dementia in a dementia …

An Assessment Of Actual Evapotranspiration And Soil Moisture Functions Based On Local-Scale Data In Alabama, Lisa Lugo Kuzy

Dissertations

Large-scale models and remote technology are widely used for the estimation of the energy budget at a global scale. The interaction of energy fluxes and soil water at the vegetation root zone is the driving force that controls the evapotranspiration process. Although the importance of soil moisture, it can only be measured at a point scale, given the great heterogeneity of soil profile. Large-scale models struggle to capture the spatial heterogeneity of soils, and remote sensing can only observe the surface level soil moisture, omitting the root zone. Studies have shown evapotranspiration estimates (specifically from Remote Sensing) and can provide …

Exploring Moral Distress Among Nurse Leaders, Preston H. Miller

Dissertations

Moral distress (MD) occurs when an individual knows the ethically correct action to take in a situation but institutional constraints prevent the individual from acting. MD is a well-documented phenomenon among nurses and occurs at a high frequency in the critical care setting. When MD is not adequately addressed and actions are not taken to mitigate precipitating factors within an organization, moral injury, moral residue, and burnout may consequentially result in nurses leaving their role or the profession. Nurse leaders are positioned to exemplify ethical leadership and provide support for their staff when MD is experienced; however, nurse leaders experience …

Measurements Of Terrestrial Gamma-Ray Flashes, Gamma-Ray Glows, And A Direct Lightning Strike From Eight Flights Of The High Energy Lightning Emission Network (Helen), Christopher Helmerich

Dissertations

The High Energy Lightning Emission Network (HELEN) campaign involved 8 balloon flights into thunderstorm environments to measure high-energy radiation phenomena like gamma-ray glows and terrestrial gamma-ray flashes (TGFs). Multiple flights detected elevated radiation levels providing evidence for theories on gamma-ray glow generation. Flight 7 measured multiple TGFs coincident spatially and temporally with lightning strikes, supporting theories of TGF origins in lightning leaders and/or return strokes. The same flight also sustained a direct lightning strike, enabling first-of-its-kind energetic radiation measurements during the propagation of the lightning strike. Radiation production was evident in both stepped leaders and return strokes, with higher flux …

Structural Impact Of Epstein-Barr Virus- Encoded Small Rna -1 On Its Transport And Function, Zubaida Hassan

Dissertations

Epstein-Barr Virus (EBV)-Encoded RNAs (EBERs) are two small, noncoding, structurally conserved transcripts that are expressed in millions of copies in all stages of EBV infection. Despite their abundant expression, the role of EBERs in EBV biology or pathogenesis is not well defined. However, they are associated with driving cell proliferation and improving intercellular communication via their secretion in exosomes. In spite of the pathogenic potentials of EBERs, the mechanisms involved in their transport and function remain to be elucidated. The aim of this PhD dissertation was to investigate the structural impact of EBER1 in its transport and function. The conserved …
